a chemical messenger secreted by glands and carried in the blood plasma

a group of specialised cells that secrete hormones

the process of physical changes that lead to sexual maturity

the process of an egg being released from an ovary

the process of the uterus lining breaking down

Hormones: puberty, the menstrual cycle and the menopause

Combined science

Hormonal control of the menstrual cycle

Hormonal and non-hormonal methods of contraception

Using hormones to treat infertility

Pupils will learn about the roles of hormones in controlling plant growth and development, including growth responses to stimuli including light and gravity.

Pupils learned about unspecialised cells in animals and plants, how they become specialised, and potential benefits and issues with using stem cells in medicine.

This unit covers the roles of hormones in reproduction, including the menstrual cycle and the effects of FSH, LH, oestrogen, and progesterone. It explains contraception methods, and fertility treatments, and evaluates their social, economic, and environmental impacts.
